NAME
Pod::Usage::Return - pod2usage that returns instead of exits
VERSION
version 0.003
SYNOPSIS
use Pod::Usage::Return qw( pod2usage );
exit pod2usage(0);
sub main {
return pod2usage("ERROR: An error occurred!") if $ERROR;
}
exit pod2usage( -exitval => 1, -message => 'ERROR: An error occurred' );
DESCRIPTION
This is a drop-in replacement for Pod::Usage "pod2usage" that returns
the exit value instead of calling exit.
RATIONALE
Testing that your command-line script works is a good thing. It's a lot
easier to test a module, so writing your command-line script as a module
("modulino") makes it easier to test.
Unfortunately, Pod::Usage automatically calls "exit", which again makes
it harder to test your script. There is a way to prevent Pod::Usage from
exiting, but it makes using Pod::Usage a lot less convenient.
This module provides a drop-in "pod2usage" replacement that returns the
exit code instead of exiting, so that you can easily test your script
while using Pod::Usage.
FUNCTIONS
pod2usage
See Pod::Usage for documentation. Returns the exit code instead of
calling exit().
